[0036] Therefore, the design scheme is designed according to the requirements: the overall appearance size should not be larger than the remote transmission module and close to the base meter (cold water meter); it should adapt to copper shells of different calibers and have a certain opening angle; during the tightening and lifting process, the connecting parts can be kept close to the cylinder of the cold water meter, and the force-bearing surface is not easy to fall off during the tightening process. The force decomposition method is used to decompose both the pulling force and part of the centripetal clamping force during the lifting process.

[0037] The cold water meter remote transmission module fixing structure of the present invention is designed according to the above design concept.

[0038] Figure 1 The front view of the cold water meter remote transmission module fixing structure of the present invention is shown. In order to more clearly show the structure of the connecting hook, Figure 1 The left side portion of FIG. 1 does not show the fastening screw and the lock nut. Figure 2 FIG. 1 shows a top view of the cold water meter remote transmission module fixing structure of the present invention. Figure 1 and 2 As shown, the cold water meter remote transmission module fixing structure of the present invention includes a connecting hook 2, a backing plate 3, a fastening plate 4, a fastening screw 7 and a locking nut 6.

[0039] Among them, Figure 3 As shown, in the present invention, the lower end of the connecting hook 2 has a bottom hook 2.1, and the upper end has an upper hook 2.2. Moreover, the angle between the lower surface of the upper hook 2.2 and the vertical surface of the hook body is less than 90 degrees. That is, the end of the upper hook 2.2 is tilted downward. In this way, Figure 7 As shown, when the end of the upper hook 2.2 is subjected to an upward thrust, it can be deformed and become flush, so as to be in close contact with the upper surface of the fastening plate 4.

[0040] Preferably, the cold water meter remote transmission module fixing structure of the present invention has a total of four connecting hooks 2 to better achieve the installation and fixation of the remote transmission module and make the installation and fixation more firm.

[0041] like Figure 4 As shown, in the present invention, the pad 3 is a square plate, and has a pad hole 3.1 in the middle for the upper part of the remote transmission module 5 to pass through. At the same time, a plurality of pad through holes 3.2 are provided around the pad hole 3.1 for the connection hook 2 to pass through.

[0042] Preferably, the pad through-hole 3.2 is a rectangular hole to facilitate the passing of the bottom hook 2.1 of the connecting hook 2.

[0043] More preferably, the pad 3 has four pad through-holes 3.2. More preferably, the four pad through-holes 3.2 are evenly arranged on the pad 3.

[0044] like Figure 5 As shown, in the present invention, the fastening plate 4 is also a square plate, and has a fastening plate hole 4.1 in the middle for the upper part of the remote transmission module 5 to pass through. At the same time, a plurality of fastening plate through holes 4.2 for the connection hook 2 to pass through and a plurality of screw through holes 4.3 are arranged around the fastening plate hole 4.1.

[0045] Preferably, the fastening plate through-hole 4.2 is a rectangular hole to facilitate the passing of the bottom hook claw 2.1 of the connecting hook 2.

[0046] More preferably, the fastening plate 4 has four fastening plate through holes 4.2. More preferably, the four fastening plate through holes 4.2 are also evenly arranged on the fastening plate 4.

[0047] In addition, preferably, the fastening plate 4 has four screw through holes 4.3. More preferably, the four screw through holes 4.3 are evenly arranged on the fastening plate 4. In this way, it can better drive the connecting hook 2, thereby ensuring that it can firmly realize the installation and fixation of the remote transmission module.

[0048] Each of the screw through holes 4.3 is provided with a matching fastening screw 7. In addition, the upper end of the fastening screw 7 is provided with a matching locking nut 6 located on the upper surface of the fastening plate 4, and the lower end is against the upper surface of the backing plate 3.

[0049] The remote transmission module 5 may be, for example, a camera direct reading module, which is in the shape of a convex frustum and has an upper portion and a lower portion.

[0050] When the remote transmission module fixing mechanism of the cold water meter of the present invention is used to install the remote transmission module on the cold water meter, Figure 1As shown, the lower surface of the remote transmission module 5 is first installed on the upper surface of the glass cover of the cold water meter 1. The pad 3 is installed on the upper surface of the lower part of the remote transmission module 5. The fastening plate 4 is located above the pad 3. The upper part of the remote transmission module 5 passes through the pad hole 3.1 of the pad 3 and the fastening plate hole 4.1 of the fastening plate 4.

[0051] Next, the connecting hook 2 is sequentially inserted into the fastening plate perforation 4.2 of the fastening plate 4 and the backing plate perforation 3.2 of the backing plate 3. The bottom hook 2.1 of the connecting hook 2 is located at the lower part of the copper cover 8 of the cold water meter 1, and the upper hook 2.2 of the connecting hook 2 is located on the upper surface of the fastening plate 4.

[0052] Then, the fastening screw 7 is inserted into the screw through hole 4.3 of the fastening plate 4. Figure 6 and 7 As shown, the fastening screw 7 contacts the backing plate 3 during the force application process, and the pre-tightening force during the continuous tightening process will reversely increase the height of the fastening plate 4, that is, the fastening plate 4 is moved along the Figure 6 Move upward in the direction of arrow A. Figure 7 As shown, when the fastening plate 4 moves upward, an upward force is applied to the end of the upper hook 2.2 of the connecting hook 2. During the force-bearing process, the upper hook 2.2 tends to contact the upper surface of the fastening plate 4 with its lower plane after being stressed at the force-bearing point at the triangle, thereby achieving the purpose of automatically tightening the connecting hook 2, that is, making the upper hook 2.2 tightly hooked on the fastening plate 4. In addition, when the bottom hook 2.1 of the connecting hook 2 is stressed, it moves along the Figure 6 The direction of arrow B in the figure approaches the center, tightens the circumferential gap between the bottom hook claw 2.1 and the cold water meter 1, thereby achieving the fastening of base meters of different calibers, and then tightly buckles and hangs on the bottom edge of the copper cover 8. After continuous and uniform force is applied, the tightening force of the hook increases to complete the bottom sealing.

[0053] In the present invention, during the tightening process of the fastening screw 7, the contact point will decompose the pulling force, one part of which is decomposed into the lifting tensioning force in the vertical direction, and the other direction is limited to the centripetal force in the horizontal direction. Under the influence of gravity in the natural state, the bottom hook 2.1 of the connecting hook 2 is in a tightened state. There is no need to worry about the unhooking phenomenon during the tightening process, thereby solving the risk of repeated construction.

[0054] At the same time, the size of the pad hole 3.2 of the pad 3 is slightly larger than the size of the upper part of the remote transmission module 5, giving a certain degree of swing freedom so that the fixed structure can adapt to more caliber base tables.

[0055] After tightening, the locking nut 6 matched with the locking nut 6 and located on the upper surface of the locking plate 4 is arranged on the upper end of the locking screw 7. The locking nut 6 can prevent the locking screw 7 from loosening, thereby ensuring that the installation and fixing are firm.

[0056] Preferably, a gasket is further provided between the anti-loosening nut 6 and the upper surface of the fastening plate 4. In this way, the anti-loosening purpose can be better achieved.

[0057] In addition, in the present invention, preferably, the connecting hook 2, the backing plate 3, the fastening plate 4, the fastening screw 7 and the locking nut 6 are all made of stainless steel, for example, food-grade stainless steel, so as not to pollute the water source.
